ALB and type 2 diabetes mellitus: For example, for a 90-year-old CRC patient with lung metastasis, a BMI of 25 kg/m2, a history of type 2 diabetes, chronic smoking, and an albumin level (ALB) of 32 g/L, the nomogram scores are as follows: age 90 years (47.5 points), lung metastasis (32 points), BMI 25 kg/m2 (54 points), type 2 diabetes (27.5 points), smoking (27 points), and ALB 32 g/L (22 points), totaling 210 points, resulting in a 0.13 (13%) probability of myelosuppression.
